WINDOW-SASH GEARING AND LOCK.

Specification of Letters Patent.

Patented. Mar.- 1, 1921..

Application filed April 1,' 1920. SerialNo 370,423.

window sash gearing'and' lock and an'object is to provide a device of this kind wherein upon movement of one sash, preferably the lower one, the other sash is' likewise movable and also wherein one of two members or both of the gear'connections between the sashes are capable of manipulation, whereby one or both of the sashes may be locked,

either through the adjustment of one of the gear members in connection with a locking device to secure both sashes, or in connection with the locking device and through the medium of the-gear connections on the other sides of the sashes, both sashes may be locked and vice verse Another object is to provide a gearing and locking mechanism between the upper and lower sashes, which are simple, efiicient and practical in construction and may be cheaply made and sold at a reasonable profit. a

Still another object is the provision of a device of this kind, which may beapplied-to a window and sash construction, at the time of the construction of the window, or may be subsequently applied to windows in use without changing the window'constructi'on to any great degree. In fact, the application of the present invention to a windowand the sashes therein subsequently to the- -construction would merely involve the 0H setting of racks, and interposinga revoluble: shaft in bearings of the frame and between the sashes, in conjunction with adjusting gearing on the shaft for meshing with the racks'whereby both of the sashes may"besashes can be adjnste'd'for ventilation atthetopofthe window or at the bottom, oratjthe top: andbottom, and when adjusted forsueh ventilation, either'oneor'both of the sashes m ay. be locked-.-

A still further object embodies a device of this kind which, when the sashes are locked they are practically burglar proof, as the lever which operates the locking means may be so disposed that it cannot be reached by an instrument inserted under the lower sash or over the upper sash.

While the design and construction at pres ent illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further. features.

and combination of parts, aswill be hereine after set forth, shown in the drawings and claimed.

Referring; tothe drawings; 1 designates the window -'frame which may 'be' of the usual.

construction," and 2 and 13 denote the upper cent the extreme side edge of the left hand side rail of the 'lowersash. Bythis arrange and lower sashes, which are mounted in the usual guides 4 of the frame.

Secured to the adjacent' l aces oi the side rails of the upper and lower sashes are rack bars 5 and 6, there bein two adjacent each side of the window and one carried'by the upper sash and the other by the lower sash.

ment it will be noted that the rack bars of one pair are offset in one direction, while the 4 rackbars of the other pan' on the other slde of the sashesare offset in a different direction.

Mounted in bearings of the window frame is an operatingrevoluble shaft 8 and mounted upon the shaft adjacent the oppositesides of the sashes are sliding pinions "or gears 9 and 10; Each pmlon 1s elon-' .30

gated so as to engage one or both of its ofi'setrack bars so that the sashes'may be I adjusted andlocked. For. instance, thepinvion or gear 9 is capable of meshing with "both rack bars and in such an in'sta-nce the two sashes are'movable by operating one of them. The same thlng is true in regardto the pinion or gear 10 when in engagement with its ofic'set rack bars. The innerfaces of the stiles or opposite sides of the wmdow frame are provided with lugsor teeth '11 and 12. Each pinioiror gear is sufficiently elongated so as to protrude through the side or stile of v the Window frame, andis provided with an annular groove 13. Op-

crating levers 14: and 15 are pivotally mounted'as at 16 to the stiles of the window frame and are provided with forks 17 for engagement with the grooved ends of the elongated gearsor pinions whereby upon movement of the levers, one in one d1rec-' tion, and'one in the other direction, and vice versa, the 'pnnons or gears may be ad justed, either in engagement with both sets "jofrack bars or in engagement with either one of the rack bars of the sets thereof, so

that either one or both of the sashes are adv.

justable, and so that either one or both of the sashes may be locked.

It will be noted thatthe lugs or teeth 12 and 11 are so locked asto be engaged by the teeth of the pinions soas to lock the pinions against rotation, thereby either permitting the sashes to have free movement or permittin the sashes to be locked. The levers 14 and lo are provided withhandgrip opera'ted do 's 18 to en a e the se ment racks C) b b b 19 in order to hold the levers in differentadjusted positions.

Referring to the right hand side of the window it will be noted that by the adjustment of the pinion or gear 9, it may be engagedavith' both of the rack bars 5 and 6 and should the other pinion 10 be likewise en gaged with its respective rack bars the two sashes are capable of movement by the operation of one of the sashes. However, should the pinion 9 be moved so as to engage the rack bar 5 and at the same time engage the lug or looking tooth 11,the upper sash is held against movement and it will be noted that in this instance if the otherpinion orgear 10 remains in mesh with both of its respective rack bars without engagement with its respective locking tooth, the lower sash may be moved independently. However, should the pinion or gear 10 be shifted so as to engage its re spective rack 6 of the lower sash and in turn engage the locking tooth, and if the pinion 9 still remains in. engagement with its rack 5 and its locking tooth, the two sashes are locked. It will. benoted that before moving the pinion or gear 10 so as to engage its respective locking tooth, the lower sash may be openeda short distance and-then the gear or; pinion lOshitted to engage itslocking tooth,and irrthis casethe upper sash will be held in aclosed locked position, while the lower sash may be held inan open locked position, thereby mrmitting ventilation at the bottom of the window. This same result can be attained in regard to the manipulation ofthe gear 10 on the opposite side oi the window, and-the upper sash locked in an open position and the lower sash locked ina' closed position. This is accomplished'by shifting the gear 10 so as to engage itsloeking tooth and remain in engagement with the rack bar'G of the lower sash and then before moving the pinion or gear 9 to engage its locking tooth, the upper sash may be adjusted to an open positlon afterwhich the'gear or pinion 9 may be shifted to operate into engagement with its tooth, hence locking the upper sash in an open position, whereby permitting ventilation at thetop of the window. It will also .be noted that the gears or pinions 9 and 10 can be so adjusted and looked that both sashes can be locked in open positions whereby ventilation at the top and bottom of the window may be attaine 7 It is to be understood that a device of this kind may be applied to all constructions of windows and particularly windows of housed-in sleeping porches and the like, and also in connection with windows of sanatoriums and like places. Furthermore,

by the provision of a device of this kind, either one or both of the sashes may be opened a very small-degreesothat the-ventllation of the room may easily controlled.

Also it isto be" remembered that the position of the rack bars may be reversed to that shown, and madeofany proportion, and furthermore the pinionsor gears may be of any diameter or length and also the locking tooth for each pinion may be modified as found convenient during the course of construction of the window as well as during the application. of the device. Moreover, any othersu'itable means'may be employed for'shifting the gears'or pinions. In otherwords it is not the aim to confine the invention to the particular form of lever.

In fact other means instead of the lever may be employed forshiftifig the gears.

As illustrated in Fig. 1 it will be noted that the side stiles of the window frame are provided with movable holding strips 22, which are pivotally mounted upon screws, so that by detaching the upper ends of the strips by removing the retaining screws 24 the strips 25 may be swung outwardly to permit one of the sashes, preferably the lower one to be swung outwardly and the rack bars of the lower sash to disengage from the pinions. In this case, the other sash is capable of movement independently. This same principle may be employed with the other face if so desired, it being the aim to limit the use of this principle to one sash only. These movable holding strips may be disconnected from the window frame entirely in order to permit the window sash to be removed. This same principle may be also supplied to the parting strip between the sashes. In other words, the parting strip can be removed so that both sashes may be removed from the window frame, as the parting strips 26 are detachably secured at 27 to the window frame.
